Abstract
The utility model relates to a miniature energy-saving differential pressure precooling storage which is formed by the connection of a main storage and a differential pressure chamber. A partition which is connected with the main storage and the differential pressure chamber is provided with an air cooling machine of a refrigerating machine set and a plurality of differential pressure doors, and each differential pressure door is provided with a differential pressure adjusting valve. Each differential pressure adjusting valve is a water gate type adjusting valve, and is provided with a slide way and a lifting rope, wherein the lifting rope passes through the pulley above the lifting rope and the other end of the lifting rope is provided with a balance weight. The miniature energy-saving differential pressure precooling storage can realize differential pressure ventilation and precooling, and has the function that a packing case with a ventilation hole can be stacked by a special mode. Differential pressure fans are used on both sides of the packing case to cause pressure difference, so that cool air in the storage can pass through the inside of the packing case to directly contact the surface of vegetables for refrigeration. The degree of the opening of the water gate type differential pressure adjusting valve can be adjusted to adjust the air quantity. The utility model has the characteristics of high precooling speed and energy saving, and is favorable for the preservation of fruits and vegetables.
Description
Technical field
The utility model belongs to miniature pre-freezer, particularly a kind of miniature energy-conservation differential pressure precooling storehouse.
Background technology
Do not have air to flow in the middle of the fruits and vegetables of being stacked in the present existing miniature fresh-keeping ice house, the temperature of fruits and vegetables can not be consistent with freezer timely and effectively like this, can not reach fresh-keeping effect.Especially just having put into fruits and vegetables can not cool down fast, influences fresh-keeping effect like this.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of miniature energy-conservation differential pressure precooling storehouse is provided.
The technical solution of the utility model is:
A kind of miniature energy-conservation differential pressure precooling storehouse is characterized in that: be connected with the pressure reduction chamber by master library and form, air-cooler and a plurality of pressure reduction door of refrigeration unit arranged on master library and the partition that the pressure reduction chamber is connected, the pressure-difference valve door is arranged on the pressure reduction door.
The pressure-difference valve door is the sluice type control valve, and the valve slideway is arranged, and lifting rope is arranged on the valve, and lifting rope is by the pulley of top, and the lifting rope other end has counterweight.
The utility model effect is:
Differential pressure ventilation precooling can be realized in this miniature energy-conservation differential pressure precooling storehouse, it is by carrying out the particular form pile to the packing case that has air vent, use the differential pressure blower fan poor, make that cold air passes through from packing case inside in the storehouse, directly contact vegetable surface and cool off at the both sides of packing case build-up of pressure.Also can regulate air quantity, blast by to the open size of sluice type pressure-difference valve door.Be characterized in that precooling speed is fast, effective, energy savings helps preserving fruit and vegetable utilizing.

The specific embodiment
A kind of miniature energy-conservation differential pressure precooling storehouse is connected with pressure reduction chamber 2 by master library 1 and forms, and air-cooler 3 and a plurality of pressure reduction door 4 of refrigeration unit arranged on master library and the partition that the pressure reduction chamber is connected, and pressure-difference valve door 5 is arranged on the pressure reduction door.
The pressure-difference valve door is the sluice type control valve, and valve slideway 6 is arranged, and lifting rope 7 is arranged on the valve, and lifting rope is by the pulley 8 of top, and the lifting rope other end has counterweight 9.
The realization of differential pressure ventilation precooling is by the packing case that has air vent is carried out the particular form pile, uses the differential pressure blower fan poor at the both sides of packing case build-up of pressure, makes that cold air passes through from packing case inside in the storehouse, directly contacts vegetable surface and cools off.Its coolant mechanism and the type of cooling are as scheming:
In freezer pressure reduction chamber, the directly strong cold wind that evaporimeter is sent, the air grid that is passed through the hyperbaric chamber by-5～-7 ℃ of low temperature that export forms-2～-1 ℃ middle warm air, rely on pressure reduction compound evenly to the fruits and vegetables ventilation of stacking, make low temperature cold air balanced flow through the storage product, return evaporimeter after the cold and hot convective exchange.Thereby can reduce evaporator defrost 20%～30%, realize energy-conservation 20%～30%, precooling synergy 30%～40%.The storehouse body is realized the differential pressure samming, and the environment temperature field wave moves Δ T＜0.5 ℃.Reached the fruits and vegetables precooling 6 hours, the product temperature drop is to 6-9 ℃, and the surface is fresh, and quality descends＜5%.
Shown in Figure 4 is that the miniature energy-conservation differential pressure precooling of a kind of use storehouse fruits and vegetables are piled up the form plane, the master library of the pressure reduction door 4 between master library 1 and pressure reduction chamber 2 on one side, the packing case U font that fruits and vegetables is had air vent is piled up, and makes its cold wind evenly pass each vegetable and fruit packaging case.
Shown in Figure 5 is that the another kind of miniature energy-conservation differential pressure precooling storehouse fruits and vegetables that use are piled up the form plane, the master library of the pressure reduction door 4 between master library 1 and pressure reduction chamber 2 on one side, the packing case in-line that fruits and vegetables is had air vent is piled up, and makes its cold wind pass each vegetable and fruit packaging case successively.
Claims (2)
1, a kind of miniature energy-conservation differential pressure precooling storehouse is characterized in that: be connected with the pressure reduction chamber by master library and form, air-cooler and a plurality of pressure reduction door of refrigeration unit arranged on master library and the partition that the pressure reduction chamber is connected, the pressure-difference valve door is arranged on the pressure reduction door.
2, miniature energy-conservation differential pressure precooling according to claim 1 storehouse, it is characterized in that: the pressure-difference valve door is the sluice type control valve, and the valve slideway is arranged, and lifting rope is arranged on the valve, and lifting rope is by the pulley of top, and the lifting rope other end has counterweight.
